UNITED STATES ABNER JUDSON MGGEHEE, OF JACKSON, TENNESSEE.

GASOLEN E SERVICE-TAN K.

Application filed August 30, 1919.

To all whom it may concern:

Be it known that l, ABNER J. MGGEHEE, a citizen of the United States, and a resident of Jackson, in the county of Madison and State of Tennessee, have invented certain new and useful Improvements in Gasolene Service-Tanks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in gasolene service tanks, the object being to provide a simple and inexpensive device that will be absolutely reliable and quickly deliver a measured amount of gasolene to a motor car, the amount to be delivered being visible to the purchaser, and it consists in a graduated dispensing tank elevated so as to deliver to the car by gravity, and means for elevating the gasolene from a larger reservoir, preferably located under ground, to the dispensing tank by the operation of compressed air, thus securing quick action and dispensing altogether with the expensive pumping apparatus in common use for that purpose. I My invention further consists in the parts and combinations of parts as will be more fully explained and pointed out in the claims.

The accompanying drawing is a view in vertical longitudinal section of my improved apparatus.

1 is the main reservoir, which in the present instance is shown under ground and 2 is a pipe leading from the main tank to a three way coupling 3, also underground. Communicating with the topof the coupling 3 is a pipe 4 which extends above the surface of the ground and is open at its upper end. Surrounding the open end of pipe 4 is the dispensing tank 6 preferably cylindrical in form and closed at its upper end by the head 6 which is provided centrally with a threaded opening into which is screwed the nut 7 having a depending ring shaped beveled seat 7? located immediately above the open end of pipe 4.

8 is a float preferably perforated and located within the tank 6 and provided with acentral opening for the pipe 4 and with an upwardly projecting ring shaped valve 8 conforming in diameter and position to the beveled seat 7* on, the nut and beveled at Specification of Letters Patent.

its upper end to make a sealing joint with the beveled end of the seat 7 This valve 8 snugly embraces the pipe 4 so as to prevent the passage of any appreciable quantity of gasolene down between it and the pipe, but it should have a free sliding movement on the pipe so that it and the float 8 may rise and fall with the rise and fall of gasolene in the tank 6. The valve 8 is of such length that when seated against its seat 7, its lower end or the float carrying it, will be below the upper open end of the pipe 4 and thus shut off the flow of gasolene to the tank 6.

The tank 6 which is supported on the stand 5, is graduated to indicate the contents in gallons, and is made of glass, or

other transparent material, or is provided with an opening throughout its length covered with glass or other material, or with a sight tube, so that the height of the contents of the tank will be clearly visible, and may be seen by the customers. This tank is seated on the top of stand 5 and may be inclosed in a wire or perforated casing, or by bars to protect it against accidental blows, and is provided at its bottom with a reduced neck connected by coupling 9 with the discharge pipe 11, to which the discharge hose (not shown) is attached, the pipe 11 being provided with a valve 10 for controlling the discharge of fluid from dispensing tank 6.

12 is a pipe leading from an air reservoir, compressor or other source of air under pressure. This pipe 12 is preferably located underground and passes upwardly in stand. 5 to a point within easy reach of the operator and then downwardly, under and into the three way coupling 3, its open end being in a plane above the level of the connection of pipe 2 with the coupling and below and in the vertical plane of pipe 4. This pipe 4 is provided preferably in the bend atits upper end with the valve 13, this valve and the valve 10 being accessible through a door 15 in the front of casing 5, so that when the door is locked the valves will be concealed and inaccessible.

Pipe 4 passes through coupling 9 attached to the lower end of dispensing tank 6, and through the restricted opening in the lower end of said tank, ample space however being left around the pipe 4 for the passage of the gasolene to the discharge pipe 11.

' All up to date servicestations have a compressed air reservoir and pumps for it, for inflating tires, and I take advantage of such apparatus for supplying air to the gasolene dispensing apparatus.

Normally the dispensing tank is empty and gasolene standsin the-pipes 4: and 12 up to the level of the gasolene in the main tank 1, the coupling 3 being always full of oil, hence when the air pressure is let into the vertical leg of pipe 12 by opening valve 13, the pressure acting on the column of gasolene forces it down pipe 12 and up" pipe a and into tank 6, the gasolen-c in the main tank flowing into the coupling 3 as fast the column is forced up the pipe at into tank 6. This tank 6 is marked to indicategal-- 1 ters-Patent, is

lons, in the present instance five,'hence the operator by proper manipulation of the valve 18 can accurately control the flow of gasolene to the tank 6 and the custoiner can see the amount therein. If the operator fails to shut oil the air at the time the tank 6 is filled to its measuring capacity, the float 8 will rise andcut off further flow to the tank, and when the air pressure is cut off by the valve 13 the "gasolene in pipe 4 will seek itsnatura l level and any gasolene in tank 6 above the ,top of pipe at will'flow back into the latter. After the tank 6 has been charged with. the proper amount of gasolene desired by the customer, the air is cut off and valve 10 opened thus permitting the gasolene or any part of it in the tank 6 to gravitate into the tank on the motor.

"With thisdevice it is only necessary, when it is desired to fill the tank 6, for the operator to open air valve 13, the air pressure in the reservoir being sufficient to force the gasolene up pipe 4 and into thedispensing tank, and when the tank has been filled or partly filled further supply-can be stopped by cutting oif the air.

It is evident that numerous changes might be resorted to in the relative arrangement of parts shown and described without departing from the spirit and scope of my insupply to thethree way coupling and discharging into the latter, a valve in said air pipe, a dischargepipe from the dispensing tank and a valve in said latter pipe;
